19. Radial Land With radial land surfaces, friction is enhanced, reducing the mechanical resistance of the files. An attempt has been made to lower the friction, thus creating a kind of recessed radial land (Quantec and K3 instruments). This helps to prevent the propagation of cracks and reduces the chances of separation and deformation from torsional stresses. Rotary …
